This is a single screw Doser system with a hopper capacity of 0.5m3.
The machine has a small footprint, with a modular design making it easy to transport and very simple to assemble on site.
The machine has a hopper for fresh concrete with a dispensing auger in the bottom which operates on a timer to give a measured quantity of concrete each time it is activated.
The hopper has a vibrator fitted to assist the flow of concrete during operation.
The dispensing auger is driven by a precision roller chain with a simple adjustment mechanism.
Dispensing can be controlled by hand switch or foot-pedal either manually or automatically with vibration on demand.
The control panel houses the control switches and the isolator and an emergency stop button.
The machine is designed to dispense typical precast concrete.
It is important to ensure the mix is cohesive and has a suitable slump. The use of a superplasticiser will dramatically improve the mix properties and reduce wear on the delivery auger and will help early strength development.
